Solution: Convert Sorted Array to Binary Search Tree

Explore how to convert a sorted array into a height-balanced binary search tree by using recursive depth-first search methods. This lesson helps you understand the step-by-step approach to choose middle elements as roots and build balanced left and right subtrees, optimizing tree height and structure for efficient search operations.

We'll cover the following...

Statement

Given an array of integers, nums, sorted in ascending order, your task is to construct a height-balanced binary search tree (BST) from this array.

In a height-balanced BST, the difference of heights of the left subtree and right subtree of any node is not more than 1.

Note: There can be multiple valid BSTs for a given input.

Constraints:

...
